CubeCell (TM) is a new product series made by Heltec team, mainly for LoRa/LoRaWAN node applications.

CubeCell (TM) series is based on ASR605x (ASR6501, ASR6502), those chips are already integrated with the PSoC^® 4000 series MCU (ARM^® Cortex^® M0+ Core) and SX1262. We have done a lot of migration and development, made it perfectly support Arduino^®, can run the LoRaWAN protocol stably, can easily connect lithium batteries and solar panels.

HTCC-AB02A is a Dev-Board. Friendly designed for developers, easy to verify communication solutions.

HTCC-AB02A is a part of the “CubeCell“ series, with the following features:

Perfect Arduino-Compatible!
CE and FCC certification;
Based on ASR605x (ASR6501, ASR6502), those chips are already integrated the PSoC^® 4000 series MCU (ARM^® Cortex^® M0+ Core) and SX1262;
LoRaWAN 1.0.2 support;
Ultra low power design, 3.5uA in deep sleep;
1/2 AA battery shell, use 1/2 AA Lithium chlorine sulfite battery (this battery can’t charge, but onboard USB / battery power automatic switching allows connect USB when the battery is assembled);
Micro USB interface with complete ESD protection, short circuit protection, RF shielding, and other protection measures;
Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
Good impendence matching and long communication distance.
